BACKGROUND

[0001] 1. Technical Field

[0002] The present disclosure relates to a server chassis.

[0003] 2. Description of Related Art

[0004] Server chassis can comprise tower or rack form factors. The tower
chassis commonly requires support by only footpads, while the rack
chassis requires none. However, in many cases, footpads are difficult to
disengage from the chassis; and as a result, the tower chassis may not
convert to a rack form factor, which is inconvenient.

DETAILED DESCRIPTION

[0013] The disclosure, including the accompanying drawings, is illustrated
by way of example and not by way of limitation. It should be noted that
references to "an" or "one" embodiment in this disclosure are not
necessarily to the same embodiment, and such references mean at least
one.

[0014] Referring to FIGS. 1 and 2, an exemplary embodiment of a chassis
includes a baseboard 10 and a plurality of footpads 20 mounted on the
baseboard 10.

[0015] The baseboard 10 forms a plurality of fixing portions 12. Each
fixing portion 12 includes a depressed portion 14 defined in a center of
the fixing portion 12, and a plurality of fixing holes 18 defined in the
baseboard 10 around the depressed portion 14. A through hole 16 is
defined in a bottom of each depressed portion 14.

[0016] Referring to FIGS. 3 and 5, each footpad 20 includes a fixing
member 22, a receiving member 30, a movable member 40, and a spring 50.

[0017] The fixing member 22 includes a rectangular top board 24 and four
side boards 26 perpendicularly extending from four sides of the top board
24. A through hole 240 is defined in a center of the top board 24. Two
fixing plates 28 extend away from each other from distal ends of two
opposite side boards 26 of the fixing member 22. Two spaced fixing holes
280 are defined in each fixing plate 28.

[0018] The receiving member 30 includes a substantially circular top plate
32, a curved extension portion 320 extending from a part of a
circumference of the top plate 32 and coplanar with the top plate 32, a
first sidewall 342 extending from the other part of the circumference of
the top plate 32, and a second sidewall 340 extending from a
circumference of the extension portion 320. Two connection portions 344
are connected between corresponding ends of the first sidewall 342 and
the second sidewall 340. A slide slot 331 is bound by inner surfaces of
the connection portions 344 and the second sidewall 340. A blocking
portion 36 extends from sides of the first and second sidewalls 342 and
340 opposite and parallel to the top plate 32. A first post 321 extends
from a center of an inner surface of the top plate 32, and axially
defines a through hole 324 extending through the top plate 32. An end
wall 323 of the first post 321 opposite to the top plate 32 defines a
through hole (not labeled), communicating with and smaller than the
through hole 324 of the first post 321. Two latches 326 extend up from an
outer surface of the top plate 32, at opposite sides of the through hole
324. Two substantially sector-shaped first protrusions 328 are formed in
the inner surface of the top plate 32 at opposite sides of the first post
321. Each first protrusion 328 is located adjacent to a conjunction of
corresponding ends of the first and second sidewalls 342 and 340. The
first protrusion 328 includes two angled surfaces 329 at opposite sides
of the first protrusion 328. A slot 330 is bounded by the first and
second sidewalls 342 and 340, and each corresponding first protrusion
328.

[0019] The movable member 40 includes a substantially circular base plate
42 and a sidewall 44 extending from the circumference of the base plate
42. A blocking bar 434 perpendicular to the base plate 42 extends from an
outer surface of the sidewall 44. The base plate 42 defines a circular
depressed portion 420 in a center of an outer surface of the base plate
42, opposite to the receiving member 30. An operation bar 422 is
connected between opposite sidewalls of the depressed portion 420,
thereby dividing the depression portion into two semicircular parts. A
second post 424 towards the top plate 32 of the receiving member 30
extends from a center of an inner surface of the base plate 42, and
axially defines a threaded hole 430 therein. Two substantially
sector-shaped second protrusions 426 protrude from the inner surface of
the base plate 42, at opposite sides of the second post 424. An end of
each second protrusion 426 away from the second post 424 is connected to
the sidewall 44. A second slot 330a is defined between each second
protrusion 426 and the post 424. Two substantially wedge-shaped
projections 432 with angled tops are respectively connected between tops
of the second protrusions 426 and the inner surface of the base plate 42,
located at opposite sides of the second post 424.

[0020] Referring to FIGS. 4 and 6, in assembly, the fixing plates 28 of
the fixing member 22 are attached to the inner surface of the base board
10, with the fixing plates 28 contacting the inner surface of the base
board 10 and located at opposite sides of a corresponding depressed
portion 14. A plurality of screws (not shown) extends through the fixing
holes 18 of the base board 10 and the fixing holes 280 of the fixing
member 20, and is received in a plurality of threaded retainers (not
shown), to mount the fixing member 20 to the inner side of the base board
10.

[0021] The second post 424 (see FIG. 5) of the movable member 40 extends
through the through hole 324 from the end wall 323 of the receiving
member 30, and the first post 321 is received in the second slots 330a
between the second post 424 and the second protrusions 426 of the movable
member 40. The blocking bar 434 of the movable member 40 is received in
the slide slot 331 of the receiving member 30. At this time, the movable
member 40 is completely received in the receiving member 30, with the
first protrusions 328 of the receiving member 30 positioned at opposite
sides of the second post 424 and the tops of the first protrusions 328
contacting the inner surface of the base plate 42. The distal end of the
sidewall 44 of the movable member 40 is received in the first slots 330
of the receiving member 30. A fastener 60 extends through the spring 50
and is received in the threaded hole 430 of the second post 424, with
opposite ends of the spring 50 resisting a head portion of the fastener
60 and the end wall 323 of the first post 321. Accordingly, the movable
member 40 is pivotably mounted on the receiving member 30. The blocking
bar 434 of the movable member 40 can selectively resists against one of
the connection portions 344.

[0022] The receiving member 30 extends through the corresponding through
hole 16 of the base board 10 and enters the corresponding fixing member
22, until the latches 326 and the head portion of the fastener 60 extend
through the through hole 240 of the fixing member 22. Therefore, the
latches 326 are blocked by the outer surface of the top board 24 of the
fixing member 22 and the blocking portion 36 of the receiving member 30
is blocked by the bottom of the corresponding depressed portion 14.
Thereby, the movable member 40 and the receiving member 30 are pivotably
mounted on the fixing member 22.

[0023] Referring to FIG. 7, in use, when the chassis is to be deployed in
a tower chassis, the operation bar 422 is operated to move the blocking
bar 434 toward the other connection portion 344, with the tops of the
projections 432 of the movable member 40 sliding along the angled
surfaces 329 of the corresponding first protrusions 328, and the second
protrusions 426 contacting the tops of the corresponding first
protrusions 328. Thereby, the movable member 40 extends out from the
corresponding receiving member 30 to be supported under the base board
10. The blocking bar 434 of the movable member 40 is slid along the slide
slot 331 until resisting a first connection portion 344 of the connection
portions 344. At this time, the fastener 60 is moved toward the outer
side of the base board 10, and the spring 50 is deformed to fix the
movable member 40 in the receiving member 30 tightly.

[0024] When the chassis is to be deployed in a rack configuration, the
operation bar 422 moves the blocking bar 434 reversely, the second
protrusions 426 slide away from the corresponding first protrusions 328
and contact the inner surface of the top plate 32 of the receiving member
30. The projections 432 slide along the angled surfaces 329 of the
corresponding protrusions 328, and the second protrusions 426 contact the
inner surface of the top plate 32 of the receiving member 30. The
blocking bar 434 of the movable member 40 is slid along the slide slot
331 until resisting a second connection portion 344 of the connection
portions 344. Thereby, the movable member 40 withdraws back into the
receiving member 30 completely, and the spring 50 is restored.

[0025] It is believed that the present embodiments and their advantages
will be understood from the foregoing description, and they will be
apparent that various changes may be made thereto without departing from
the spirit and scope of the description or sacrificing all of their
material advantages, the examples hereinbefore described merely being
exemplary embodiment.
